We present a simplification algorithm for manifold polygonal meshes of plane-dominant models. Models of this type are likely to appear in man-made environments. While traditional simplification algorithms focus on generality and smooth meshes, the approach presented here considers a specific class of man-made models. By detecting and classifying edge loops on the mesh and providing a guided series of binary mesh partitions, our approach generates a series of simplified models, each of which better respects the semantics of these kinds of models than conventional approaches do. A guiding principle is to eliminate simplifications that do not make sense in constructed environments. This, coupled with the concept of "punctuated simplification", leads to an approach that is both efficient and delivers high visual quality. Comparative results are given.

Historically, the ACM Multimedia Conference is split into a "technical" program and an "arts" program. These programs sometimes seem completely separate from one another, victims of a "semantic gap" between disciplines. The goal of this panel is to create a space in which scientists learn from artists, and arts from science. We need to discover new connections between modalities of research. In order to create the most exciting and powerful future forms of interactive multimedia systems, the ones that will create the most beneficial broader impact on humanity, we need to foster new collaborations between artists and scientists. This panel seeks to bridge the great divide of language and communities that has fragmented us, creating a new space for developing connections between the arts and sciences of multimedia research, as embodied through the artists and scientists of ACM Multimedia. The goal is to make this conference a premier site for catalyzing emergent connections. Among the ancient Greeks, the techne, which included the sciences, were based in the arts. Our modes of knowledge production have since separated and grown alienated. "What weird stuff are those people doing?" To bridge the divide, we must understand and acknowledge differences, and use this as a basis for discovering common ground. In the sciences, knowledge is constructed empirically, through hypotheses and validations. Aesthetics and concepts play essential roles in how works of art are formulated to stimulate experiences. Where do these aims intersect and how might they inform each other? In this conference, one track develops pattern recognition methods for content analysis and retrieval. Another develops network and system techniques. Applications invoke these methods in usable systems. Human-centered multimedia serves as a bridge connecting human experiences with algorithmic methods. The interactive art program develops new concepts of how multimedia can function culturally, amidst society,

Modern web-based Scientific Visualization applications try to overcome common limitations imposed by limited internet bandwidth, server bottlenecks or network latency. A further aspect is the desire to gain platform independence by solely using instruments which are platform independent by conception: the programming language Java, the Virtual Reality Modeling Language (VRML), or the 3D API *** present a prototype of a hybrid web-based Scientific Visualization system which makes use of the increasing computational power of modern desktop workstations and personal computers on the client side, and the superior performance provided by a powerful machine on the server side. In order to achieve high interaction rates and to balance computational load the user can dynamically assign selected tasks to his client or to the *** the scientific field of human modeling we have implemented a hybrid web-based toolkit for the modeling of human muscles and skin. Our application allows the on-line generation and manipulation of three-dimensional implicit muscle models in a heterogeneous network and it offers various parameters to adjust computation and response time versus rendering quality.

Minimal Cases for Computing the Generalized Relative Pose using Affine Correspondences

arXiv 2020年

作者： Guan, Banglei Zhao, Ji Barath, Daniel Fraundorfer, Friedrich College of Aerospace Science and Engineering National University of Defense Technology China Computer Vision and Geometry Group Department of Computer Science ETH Zürich Institute for Computer Graphics and Vision Graz University of Technology Austria Remote Sensing Technology Institute German Aerospace Center Germany

We propose three novel solvers for estimating the relative pose of a multi-camera system from affine correspondences (ACs). A new constraint is derived interpreting the relationship of ACs and the generalized camera model. Using the constraint, we demonstrate efficient solvers for two types of motions assumed. Considering that the cameras undergo planar motion, we propose a minimal solution using a single AC and a solver with two ACs to overcome the degenerate case. Also, we propose a minimal solution using two ACs with known vertical direction, e.g., from an IMU. Since the proposed methods require significantly fewer correspondences than state-of-the-art algorithms, they can be efficiently used within RANSAC for outlier removal and initial motion estimation. The solvers are tested both on synthetic data and on real-world scenes from the KITTI odometry benchmark. It is shown that the accuracy of the estimated poses is superior to the state-of-the-art techniques. Copyright © 2020, The Authors. All rights reserved.

BISECT: Learning to split and rephrase sentences with bitexts

arXiv

arXiv 2021年

作者： Kim, Joongwon Maddela, Mounica Kriz, Reno Xu, Wei Callison-Burch, Chris Department of Computer and Information Science University of Pennsylvania School of Interactive Computing Georgia Institute of Technology Human Language Technology Center of Excellence Johns Hopkins University

An important task in NLP applications such as sentence simplification is the ability to take a long, complex sentence and split it into shorter sentences, rephrasing as necessary. We introduce a novel dataset and a new model for this 'split and rephrase' task. Our BISECT training data consists of 1 million long English sentences paired with shorter, meaning-equivalent English sentences. We obtain these by extracting 1-2 sentence alignments in bilingual parallel corpora and then using machine translation to convert both sides of the corpus into the same language. BISECT contains higher quality training examples than previous Split and Rephrase corpora, with sentence splits that require more significant modifications. We categorize examples in our corpus, and use these categories in a novel model that allows us to target specific regions of the input sentence to be split and edited. Moreover, we show that models trained on BISECT can perform a wider variety of split operations and improve upon previous state-of-the-art approaches in automatic and human evaluations. © 2021, CC BY.

The elderly represent a valid group of users who can potentially benefit greatly from engaging with technology, such as healthcare systems or playing digital games. Yet, less attention has been given to the significance of senior citizens as technology users, as compared to the common younger population. In an effort to fill in the gap, this workshop aims to investigate the design of technology for senior citizens. To provide for more focused, thus more productive discussion, we will use elderly mobile phone games as a case in point here. The overarching objective is to understand what can help to make for better and more meaningful use of interactive applications and technology by the elderly, for instance, games on the mobile phone. © 2010 Copyright is held by the author/owner(s).
